LOADING...
The Black Box LFP412 is a hot-pluggable 1000Base-X SFP fiber transceiver rated at 1250 Mbps, with an LC connector and a stated 2 km reach. It suits network administrators connecting compatible Gigabit Ethernet equipment over fiber.
Recommended For
- Network technicians connecting two compatible SFP-equipped switches or media converters over multimode fiber for a 1-Gigabit link within the module’s 2-km reach.
- IT teams maintaining Black Box networking equipment that specifically lists the LFP412 as a supported transceiver.
- Network operators who want extended diagnostics to help monitor optical-link operating conditions during troubleshooting.
- Installers deploying compatible SFP equipment in industrial or other environments where the listed -40°C to +85°C operating range is useful.
- Procurement teams sourcing a TAA-compliant transceiver for a compatible network device.
Real-World Use Scenarios
- When connecting two compatible switches across an existing multimode fiber run, install a matching LFP412 at each end to carry a Gigabit Ethernet link between network rooms or nearby buildings within the supported link distance.
- To add a fiber uplink to a compatible switch with an open SFP slot, use the LFP412 instead of a copper Ethernet run; the link can extend the network over suitable multimode fiber, subject to the cable and link distance limits.
- When a compatible SFP-equipped switch or media converter needs a replacement fiber module, the hot-pluggable LFP412 can be swapped at the device, helping restore the optical link without replacing the host equipment.
- When troubleshooting an optical uplink, use the LFP412’s extended diagnostics with a compatible host to check available optical status information; this can help narrow down link issues, though it does not identify every cable or configuration fault.
